“I gotta admit, today is a little nerve racking,” Zacky Vengeance says, speaking to Guitar World on a hot July afternoon in Los Angeles. The guitarist is preparing to head to rehearsal with his bandmates in Avenged Sevenfold, something he has done hundreds of times over their 14 years together. It wouldn’t be cause for anxiety except that, this time, things are a little different. According to Vengeance, Avenged haven’t performed live in more than a year, the longest such stretch of their career.
